Under the Spell of Spiders

Áron Kaposvári


Everyone has their own experience and memories about biology, including me. What comes to my mind is about animal life, more precisely spiders.

I think everyone has met at least one spider in their life, and supposedly knows a few things about them. Considering this, I will introduce them just briefly. Spiders are fascinating creatures known for their unique ability to spin silk and construct webs. As members of the arachnid class, spiders have eight legs and two main body segments: the cephalothorax and abdomen. Unlike insects, spiders do not possess antennae or wings. Imagine you enter your room and find a dozen spiders flying around! A terrible nightmare! Spiders can be found in almost every habitat around the world. But I have good news for people with arachnophobia: there are a few spider-free places around the world like the polar regions and deep ocean trenches. So I advise you get packed-up as quickly as you can and travel to the ”edge of the world,” Antarctica. There you are certainly safe.

Most spiders are carnivorous and rely on their silk to capture their prey. Yep, you heard it right: if you bump into their cobwebs they will eat you whole. Don’t worry, I’m just joking. Focusing on hunting, web-building spiders use different designs, such as orb webs or funnel webs, while other species actively hunt using camouflage and agility. Besides that, spider silk is renowned for its strength and flexibility; believe it or not, some types are stronger than steel wires!

Spiders play a crucial role in ecosystems by controlling insect populations, making them valuable natural pest managers. Although many of you (including me) fear spiders, most species are harmless to humans. Only a small number of them possess venom capable of causing illness, and serious incidents are rare. The places with the most dangerous ones include Australia, South America, and the United States, so be aware of the dangers in these regions and countries.

Spiders also exhibit interesting reproductive behaviors. Many females create egg sacs from silk to protect their eggs. In some species, spiderlings disperse by ballooning—using strands of silk to catch the wind and travel to new locations.  Another interesting fact is that in the case of most spiders, the females are larger and stronger than the males. Considering males, at the time of mating they may perform dancing moves in front of females or hand over a ’gift’ wrapped in silk to prevent it from being eaten by others. In case the male does not win the female’s favor, (as she is mostly bigger, you can guess it) the female spider eats the male one. (Luckily, this behavior isn’t widespread among humans.)

They range widely in size, color, and behavior, with over 48,000 species documented to date. Some examples are: Black Widow, Trapdoor Spider, Twig Spider, Goliath Bird-eating Spider and Jumping Zebra Spider.

I know that most people fear these creatures, but I encourage everyone to try to like them. It may be a great challenge because I’ve heard once that there isn’t a single moment when you are more than 10 meters away from at least one spider. I can give you some advice that helped me: try looking at a spider for a prolonged period, and you’ll see that they won’t harm you. Or give them some water and watch them drink. 😊 I’ve also heard about jumping spiders that will play with laser pointers like a cat.

All in all, spiders are unique in most fields of life, from their diets to their mating. Considering their helpful habits of clearing the environment of irritating insects, we can say that they are definitely an essential part of the ecosystem.
